package main

import (
    "fmt"
    "net/http"
)

type Handler struct {}

func (h *Handler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
    uri := r.URL.Path
    fmt.Fprint(w, uri)
    return
}

func main() {
    handler := new(Handler)
    http.ListenAndServe(":8080", handler)
}

Empty struct is not needed, closure will do https://gist.github.com/tsenart/5fc18c659814c078378d
